Funnily enough I was about to report this issue too - it doesn't look great in the driver code. My use case is using runtime PM in an MFD to communicate status to the parent devices. The subdevices are just indicating that they are idle to the parent and have no reason to do anything in a suspend or resume callback. > Alternatively, we may want to allow drivers to enable Runtime PM (by > taking the appropriate action for their subsystem, e.g. calling > put_noidle in probe and get_noresume in remove), but still not define > any runtime pm handlers (implicitly always returning a success), with > something like: This would be my preferred solution. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
